datzenmike Posted September 1, 2011 Report Share Posted September 1, 2011 I take it that it's been sitting for a while?? Does it have a stock carb on it? Quote Link to comment
Cuz'n'Chub Posted September 1, 2011 Author Report Share Posted September 1, 2011 I take it that it's been sitting for a while?? Does it have a stock carb on it? Hi datzenmike, it has set off and on,, we drove it when we first got it, and then had a head gasket blow, we broke a bolt off trying to get the head off, finally got it done, then drove it for a while , had to park it while on out of state for a while, now the clutch needs to be done, its slipping, and ,,,far as we know its got the original equipment, the carb is a hitachi 340, ,has the air pump (its froze ) so we were considering bypassing all the egr stuff, been reading on the forum here and hope to get into this more later on, thanks for the reply,,,Cuz'n'Chub Quote Link to comment

herculesinwyoming Posted September 14, 2011 Report Share Posted September 14, 2011 high idle? Make sure you check the timing. and welcome to ratsun Quote Link to comment
Cuz'n'Chub Posted September 15, 2011 Author Report Share Posted September 15, 2011 high idle? Make sure you check the timing. and welcome to ratsun Thanks Hercules and all of ya!!! for all your replies, we have been foolin' with the carburetor, it idles really fast and we turned the idle and air/fuel mixture screws, and it seems to be getting better, we changed a fuel line that was cracked ,cleaned the carb with carb spray, havent got to take it off and really clean it yet,, on the timing issue ,it wont start at all til we move the distributor( turn it clockwise) all the way ,then it starts and runs it will backfire if we dont keep adjusting the idle and fuel/air mixture screws, runs good awhile then shut it off and idle changes on its own , it has good power and after it warms up awhile it will run good. it is the Hitachi stock carb. also it has all the air pump and smog stuff on it but the air pump is froze, no belt, not sure if we should attempt to take all that stuff off, we saw some posts on here where it was removed on some of your trucks, may consider that , with ya'lls help:) really enjoying the forum working on the rust spots too, may try and get some pics up soon thanks again folks cuz & chub Quote Link to comment

You may wanna take some spare tubing and use like a stethoscope, poke around see if you can hear any hissing at vacuum connections. I hear old timers spray flammable stuff like carb cleaner, starting fluid, on hoses and connection points and listen for raised idle, which would indicate the mixture got sucked into the vacuum leak, changed the air/fuel ratio. Hmmm. Stethoscope sounds safer.... Quote Link to comment
